Abstract: An image forming apparatus is connected to a paper processing apparatus and includes an image forming unit, a nip part and a hardware processor. The image forming unit performs image forming on continuous paper being conveyed on a conveyance path. The nip part nips the paper on the conveyance path. The processor selectively performs first control and second control according to an output timing of a conveyance control signal if the signal is output from the paper processing apparatus or the image forming apparatus. In the first control, the processor notifies the paper processing apparatus of permission to start or stop conveying the paper after causing the nip part to perform a press-and-contact operation or a separation operation. In the second control, the processor notifies the paper processing apparatus of the permission without causing the nip part to perform either operation.
